Running back Brian Westbrook was medically cleared during his weekend visit with the Rams, but he left town still weighing his options, the St. Louis Post-Dispatch reported Tuesday.
"He wanted to go back (home) and think it over," Rams general manager Billy Devaney told the newspaper Monday. "We're just taking it one step at a time right now."

The Rams are seeking running back depth behind starter Steven Jackson. Kenneth Darby, a three-year pro with 61 NFL carries, is the most experienced backup currently on the roster.
Westbrook, 30, suffered two concussions last season with the Philadelphia Eagles, who released him this offseason despite his standing as the franchise's career leader in yards from scrimmage (9,785). He also ranks second in rushing yards (5,995) and third in receptions (426).
After suffering his first concussion Oct. 26 against the Washington Redskins, Westbrook missed two games, then returned for a Nov. 16 contest in San Diego. However, Westbrook suffered another concussion against the Chargers and didn't return until Week 16.
Westbrook, who also has dealt with knee, rib, ankle and foot injuries over the years, said he returned too soon from his first concussion.
